Transferred my 2 toons from Sword of Ajunta Pall to Prophecy of the Five, and I'm happy as a clam.
I had forgotten just how much fun a high pop server can be!
Seen a ton of imps, too; I'll be running the dailies in my PvP gear.
My son walked by when I started the transfer and noted how excited I was; 3 hours later he saw me playing and said "you are still smiling!".
